Study Notes
Tetrahedral Molecular Symmetry
- Perfectly symmetrical tetrahedral molecules belong to the point group Td.
- The bond angle in a tetrahedral molecular geometry is approximately 109.5 degrees.
- The bond angle for a symmetric tetrahedral molecule can be calculated using geometry principles related to spatial arrangement and steric effects.
Symmetry Variations in Tetrahedral Molecules
- Most tetrahedral molecules with lower symmetry fall under the point group C3v, indicating a three-fold rotational axis and vertical mirror planes.
Chirality in Tetrahedral Molecules
- Tetrahedral molecules can be chiral if they have four different substituents or groups attached to the central atom, resulting in non-superimposable mirror images.
